The base section 112 of each groove 110 is bounded by lateral boundary walls 126 which run substantially perpendicularly to the respective contact surface 106 and 108 and are spaced from each other by the groove width B.
As can be seen from
In order to produce the grooves 110 described hereinabove in the components 102 and 104, the groove milling device described in EP 1 990 549 A1 for example can be used.
For the purposes of connecting the components 102, 104 to one another, one or more grooves 110 and in particular grooves 110 of the type described hereinabove can be provided in each of the components 102, 104.
Provision may also be made however for just one of the components 102, 104 to be provided with one or more grooves 110 and in particular grooves 110 of the type mentioned hereinabove, whereas the other component 104, 102 has no groove 110 of the type described hereinabove, or a differently formed groove 110, one or more borings, one or more recesses, one or more projections and/or one or more cut-outs or is left in its original state.
Various embodiments of connecting device 100 for connecting components 102, 104 are described in the following.

A connecting element 130 which is insertible into a groove 110 is preferably to be understood as being a connecting element 130 that is insertible into a groove 110 which comprises a base section 112 and one or more undercut sections 114 that extend away from the base section 112 in a thickness direction 116. The one undercut section 114 or the plurality of undercut sections 114 preferably have one or more undercut surfaces 122 which are formed and arranged concentrically to the base section 112. In particular hereby, the undercut surface 122 or the undercut surfaces 122 are in the form of a section of the surface of a circular cylinder.
A connecting element 130 that is insertible into a groove 110 preferably comprises a main body 134 which comprises a base part 136 corresponding to the base section 112 of the groove 110 and one or more retaining projections 138 corresponding to the undercut sections 114.
The retaining projections 138 each comprise a curved supporting surface 140 which is in the form of an arc of a circle in longitudinal section.
In particular, the retaining projections 138 are formed such as to be non-self-cutting.
In this description and the accompanying Claims, a longitudinal section, a longitudinal direction, etc. is to be understood as being a section or a movement of the connecting element 130 in a plane in which a path of movement of the connecting element 130 lies when the element is being pushed into a groove 110.
In particular, a longitudinal section is a section taken perpendicularly with respect to an axis of symmetry of the supporting surfaces 140 of the connecting element 130.
A cross section is to be understood in particular, as being a section taken perpendicularly with respect to a longitudinal section, for example, a section taken perpendicularly with respect to a contact surface 106, 108 and parallel to the axis of symmetry of the supporting surfaces 140 of the connecting element 130.
Preferably, a cross section is a section along a plane in which the axis of symmetry of the supporting surfaces 140 of the connecting element 130 extends.
In the first embodiment of the connecting device 100 illustrated in
The guidance device 142 comprises a guidance element 144 which is arranged on a connecting element 130 and comprises one or more guidance projections 146.
In particular, the guidance element 144 is insertible into a guide groove 148 of the other connecting element 130.
This guide groove 148 comprises a guidance section 150 which is engageable by the guidance element 144 by means of the guidance projections 146.
In particular, the guidance device 142 comprises a camming guide 152 which is formed by the guide groove 148.
The camming guide 152 serves, in particular, for guiding the guidance element 144 along a given guide path.
This guide path 148 is located at varying distances from the contact surfaces 106, 108 of the components 102, 104 along the guide groove.
In particular, the camming guide 152 provides a local minimum region 154 which is surrounded by two local or global maximum regions 156.
The maximum regions 156 are surrounded by run-out regions 158 on the side thereof remote from the minimum region 154.
For the purposes of connecting the connecting elements 130 and the components 102, 104 to one another, the connecting elements 130 are firstly arranged on the components 102, 104.
In a next step, the components 102, 104 together with the connecting elements 130 arranged thereon are displaced relative to each other so that the guidance element 144 of the one connecting element 130 enters the guide groove 148 of the further connecting element 130.
In particular, the components 102, 104 and the connecting elements 130 are displaced in parallel with the contact surfaces 106, 108 of the components 102, 104.
The guidance projection 146 firstly comes into engagement with a run-out region 158 and is then guided across the maximum region 156 into the minimum region 154.
Due to the further maximum region 156 which follows upon this minimum region 154, this minimum region 154 is a stable position for the guidance projection 146 along the guide path that is formed by means of the camming guide 152.
The connecting elements 130 are thus connected to one another in a stable manner when the guidance projection 146 is arranged within the minimum region 154 of the camming guide 152 (see in particular
In principle, the guidance projection 146 together with the appertaining connecting element 130 and the appertaining component 102, 104 can also be pushed over the further maximum region 156 and then out of the further run-out region 158.
The connecting elements 130 are thus displaceable completely past each other if so required.
However, provision could also be made for the connecting elements 130 not to be displaceable completely past each other. As can be perceived from

In particular, a bearing section 192 is in the form of an annular recess 194 in the main body 134.
The annular recess 194 surrounds the securing element 176 in particular.
A region in which the main body 134 and the one or the plurality of securing elements 176 merge into one another is a predetermined break-away region 196.
In particular, this predetermined break-away region 196 is substantially circular and adjoins the bearing section 192 for example.
For example, a securing element 176 comprises a pointed end 198 which is arranged at the front with respect to the securing direction 190.
In particular, a rear end of a securing element 176 is in the form of a flat end 200 with respect to the securing direction 190.
In the initial state (initial position) of the connecting element 130 that is illustrated in
The pointed end 198 of the one or the plurality of securing elements 176 is preferably arranged to be entirely in the main body 134 and in particular arranged to be within an outer contour of the main body 134.
Due to the actuation of a securing element 176, the securing element 176 is movable along the through opening 186 in the securing direction 190 so that, in particular, the flat end 200 is moved into the main body 134, whilst the pointed end 198 is moved out from the main body 134.
In this securing position of the securing element 176 that is illustrated in
For the purposes of securely fixing the connecting element 130 in a groove 110, the securing direction 190 of the securing element 176 is oriented transversely, for example, at an angle or perpendicularly to a direction of insertion 206 of the connecting element 130.
Thus, by a process of actuating the securing element 176, the connecting element 130 is fixable in the groove 110, in particular, with positive engagement.
The previously described embodiment of the connecting device 100 and thus the securing of a connecting element 130 in a groove 110 functions as follows:
Firstly, a groove 110 of the type illustrated in accordance with
In addition, a connecting element 130 of the connecting device 100 having a shape complementary to that of the groove 110 at least in sections thereof is prepared.
In particular, the connecting element 130 is in the form of a one-piece injection moulded component.
One or more securing elements 176 of the connecting element 130 are preferably provided in the initial position and are thereby connected in one piece manner to the main body 134.
In the initial position of the one or the plurality of securing elements 176, the connecting element 130 is slid in the direction of insertion 206 into a groove 110 until the main body 134 of the connecting element 130 is arranged in a given position.
Next, the securing elements 176 are actuated for the purposes of anchoring the main body 134 in this position.
To this end, the (not illustrated) operating device is placed on the one or the plurality of bearing sections 192 of the connecting element 130.
The securing elements 176 are then actuated by a process of actuating the operating device, in particular, by applying an actuating force.
In particular thereby, the securing elements 176 are subjected to a force that is effective in the securing direction 190, for example, in that a thrust force is exerted on the flat end 200 of the respective securing element 176 by means of the operating device.
Due to this application of force, the predetermined break-away region 196 between the main body 134 and the respective securing element 176 is destroyed.
The one or the plurality of securing elements 176 are thus detached from the main body 134 and thereupon moved in the securing direction 190.
It is ensured that the securing elements 176 are moved in the given securing direction 190 by means of the guide section 188.
As can be perceived especially from
Preferably, the securing elements 176 are moved to such an extent that the securing elements 176 are arranged partly in the main body 134 and partly in the component 102.
The securing elements 176 thereby produce a locking effect for the main body 134 with respect to the direction of insertion 206 in order to finally fix the main body 134 in the groove 110 in the desired position.
For example, an additional actuation of one or more securing elements 176 can be effected by means of an auxiliary pin 182 or an auxiliary bolt 184 (see in particular,
In particular, such an auxiliary pin 182 or auxiliary bolt 184 can be used for moving the securing element 176 entirely out from the main body 134 and into the component 102.
For example, (yet) firmer anchorage of the connecting element 130 in the groove 110 can be realised by means of such an auxiliary pin 182 or such an auxiliary bolt 184. As an alternative or in addition thereto, an additional functional component such as a stop element 160 for example can be arranged on the connecting element 130 by means of such an auxiliary pin 182 or such an auxiliary bolt 184.
As has already been previously explained,
In particular in regard to the remaining shape and functioning of the main body 134 for the fixation thereof in a groove 110, the embodiment illustrated in
Due to the fact that the connecting device 100 preferably comprises a main body 134 and one or more securing elements 176 that are formed in one piece with the main body 134, there is provided a connecting element 130 of the connecting device 100 which is easy to handle and reliably fixed.
